: I have turned on extglob in bash, but it behaves very strange when I

:
: shsvr:/home/tom/tmp/test1$ echo $SHELL
: /bin/bash
: shsvr:/home/tom/tmp/test1$ shopt -s extglob
: shsvr:/home/tom/tmp/test1$ ls *

: -rw-r--r--    1 tom     msc             0 Feb  1 15:47 s.File2.java
:
: shsvr:/home/tom/tmp/test1$ find .  -name !(s.*.java)

This expanded to find .  -name File1.java File2.java Makefile SCCS

-name doesn't support extended globbing and the patterns should be quoted
to avoid unintended expansion by the shell.  What you really want is:

   find . ! -name 's.*.java'
